Traffic sign pushing method based on cognitive psychology

Abstract

The invention discloses a traffic sign pushing method based on cognitive psychology, and the method comprises the steps: 1, determining each key node in an underground road network, arranging laser projection equipment at the key node of the road network, and constructing projection content information of the laser projection equipment; 2, arranging a base station and a control base station in front of the laser projection equipment with cognitive distance intervals at the key node of the road network, and constructing a broadcast data packet of the base station; 3, sending a broadcast data packet by the base station at each node of the underground road network, and receiving the broadcast data packet by vehicle-mounted navigation equipment through a Bluetooth function; and 4, after receiving the broadcast data packet, the vehicle-mounted navigation equipment synchronously sending activation information to the roadside control base station, the laser projection equipment projecting thestored key node sign information on the road, and the projected traffic sign information disappearing. Clear traffic sign information is given to drivers under the condition that the sign layout space in the underground road network is limited, so that the psychological nervous emotion of the drivers is relieved, and the traffic safety of the underground road network is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method for pushing traffic signs based on cognitive psychology, which is applicable to road networks of underground roads in various cities. Background technique [0002] In recent years, with the unprecedented development of urban road construction in my country, urban roads and road networks have gradually formed and gradually become limited, while underground road engineering is being increasingly adopted by major cities due to the advantages of land saving. As urban underground roads gradually form a network, they play an increasingly important role in the development of urban economy. Traffic safety facilities belong to the infrastructure of the underground road network, which play an important role in reducing the probability of accidents, improving road service levels, and providing sight guidance. Traffic signs are an important part of traffic safety...

Problems solved by technology

This kind of method does not get rid of the idea of ​​traditional traffic signs, the optimization effect is not obvious and it is easy to generate new interference (such as light pollution)
